Influence of the Parasitic External Electromagnetic Field on the Efficiency of a Photovoltaic System
El-Khanssa Kechar,El-Bahi Azzag,Abdelhamid Ksentini 한국전기전자재료학회 2019 Transactions on Electrical and Electronic Material Vol.20 No.5
The aim of this work is to study the eff ect electromagnetic disturbances issued from high voltage–power stations of a given power on the performance of photovoltaic panels placed at diff erent distances from sources emitting electromagnetic radiation the tests were carried out under real conditions in the region of Annaba for a power line 400 kV high voltage connecting to Ramdane Djamel to Cheffi a, the obtained results allowed analyzing the current–voltage, power–voltage characteristics in the presence of the electromagnetic fi eld. For a better characterization of the photovoltaic generators, we study the electrical power delivers by the photovoltaic generators to an external charge and we deduce the conversion effi ciency of the photovoltaic system with a maximum power point tracking command for 09 h depending on the intensity of the electromagnetic field. The experimental results make it possible to check the infl uence of parasitic radiation on the photovoltaic system with the proposed controller.
